Application filed September '29, 1908. Serial No. 455,294.

To whom it vmay 'concem:

it knownfthat 1, JOHN R. NYE, a citiof thallniterl States, esiding at VVaterville, in the county of Kennebec and State of Maine. have invented certain new and lniprovcmentsv 1n Carburetors, of

carhu'eter, which will produce a car-- cl an: ror illuminating,

poses, from a very cheap oil such e gasolene.

illustrate my invention, attention is invited to the accorngcianying drawtil-WliJlQlZZ-- ignre 1 is aplan view oi? the complete Fig, is a vertical central section view of the carhureter. Fig. 3 is a dc- Fig. section on line new, of Fig. the bottom. Figs. and (3 tail views at various parts of the ca"- to drawings -the numeral hates the outer easlrg of the carbur. which is provided with the removable or liilounted in the bottom of the easis the spiral strip 3, which provides al chai'niel 4 beginning at a point near the periphery of the hottorh and terminating a small chamber 5', in the center. Enterinc; the casing near the bottom from one side is the air inlet pipe ti whose end 7 projects beyond the center of the casing, but whose vertical pipe 8-, progects upwardly centrally thereof to apolnt near the top of the drum. in proyecting end 7, ot the pipe 6, is mounted the sprlng actuated. valve block 8,

:rpose of which will presently appear. einovahly mounted in the casing so that S provided thcrearounch is a res ,tlrum, 10, which is provided with a 1 (lltlls' l]. of heavy thick cloth, or of material,gvhich prevent the air from passing therethrouga, hut allowsithe oil to 'nereolate to the bottom of the casing.

7 perched between these disks, is an a bent lnatcrial 12, such as sponges or elsiorl, this packing torlioing a porous. rei whereby the gasolene or oil which after leaving; the upper c pipe 8 is caught and allowed to w toward the bottom of the drum,

cookin and" the air contained within the tank practically surrounding the druni and thereby coming into contact with the gasolene or oil, and becoming to a great extent carbureted. The pipe 8 projects upwardly through the center of this drum, terminating above the upper disk 11. and Within the upper end of the drum, and as the oil is drawn through the pipe 13 in the lower end of this pipe,l by the action of the air therethrough, the same is carried through this pipe, and by the action of the air, is sprayed upon the top disk 11, from whence it percolates toward the bot tonu the oil which has not been vaporized,

falling. into the spiral channel 4, while the carbureted air passes around and within the drum into the space 9, and thence up wardly into the top of the casing, above the drum l0, and out of the supply pipe 15, to be burned.

in order to feed the oil to the casing, I employ the oil tank 16, which is'providcd with the pressure teed pipe ll", which is in coinnuinicatimi with the carburetor and the tank l6 at the top of the tank 16, the oil passing through the pipe '18 into the hottonr of the carburetor, Where the entrance end 19 of the pipe 15 controlled by the float actuated valve 20, the float 21 of which, when the oil has attained the proper level in the bottom of the carbureter closes the entrance I 7 v I pipe- 19, and prevents the Oll from flowing untll more is needed. The pipes 17 and 18 ure'provided with globe valves 22 and $23,215

shown, thus making it. possible to regulate to anicety the flow of airlto the tank and consequently the fiow' of oil to the carbureter. By this means the tank may be entirely cut-off from the carburetor,when filling the tank with oil.

By means of the spring actuated block valve 8, more or ilcss oil may be taken up into the verticalpipc, regulated entirely in, accordance to the amount or pressure of the air, the greater the pressure of the air acting upon the outer end of the valve and causing its spring to be compressed and the valve to inove, so as to present a larger open ing in the lower end of the pipe 8,.the spring having a tendency to hold the valve closed.

From the foregoing description taken in connection with the drawings, the operation of my carbureter is readily understood, but hrictly stated it is, as tollowsz lhc tank 16 first filled with the oil, such as gasolene, and their air, or if desired, the regular pipe city gas, is admitted to the carbureter, through the pipe 6, suttlcient pressure being attained to cause the block valve 8, to be moved to allow the air or to pass upwardly through the pipe 8, into the to of the drum and carbureer. The air or gas during this passage, draws along with it, the Oil from the channel 4-, through the pipe 13, thus becoming carbureted, the carbiireted air passing out of the. pipe 15, While any oil, not evaporated, falls upon the upper disk of the drum and percolates through the absorbent material, some however, I find by erperii'nenls even while held in suspension in the absorbent: material is taken up by the air, which also surrounds the drum and to a certain extent is Within the drum, but that which is not evaporated falls into the chair nel l, to be again carried up through. the W hen there is no How of air or gas through the pipe 15, the pressure becomes static within the carbureter, and as the air is lighter than the oil, the air is conveyed through the pipe l? in to the tank 16, at its upper end, and thus oil is fed automatically from the tank to the channel l of the carburetor. l have found that by employing a drum 10 open at its bottom and top, gives :t'air results, and is really operative, but to secure better results the upper end of the drum 10, should be closed, thus forcing the air downward through the drum and finallv upwardly through the space 9' to the pipe 15.

This-drum will be covered inanother application. The :t'an ll, l: have found, is caused to rotate by the flow of ai and oil there against, thus assisting in forming carluncted an.

What I claim, as new 1. combination with a liquid hydro carbon supply tank and an air supply, of a carburetor, ctnuprisingx casing having a, central vertical pipe extending from near the bottom to near the top, an air supply pipe entering the casing and in c0rnmunication with the vertical pipe, a spring con-- trolled valve at the junction of the two pipes, a drum rcmovably mounted in the casing and having the upper end ot the vertical pipe terminate Within and below its upper end and providing an annular space in coinmunication with the upper and lower ends of the casing, 21 series of disks mounted in the drum and having openings therein, said openings beingarranged in zigzag order, loosely packed absorbent packing Within. the spaces between the disks, means for feeding the 'tluid to the lower space of the carbureter, and a pipe leading from Within near the bottom of the'carbureter to the top of the fluid. supply tank, as and for the purpose set forth.

2. ln combination with a liquid hydrocarbon supply tank and an'air supply, oi a carburetor, comprising a casing, a vertical pipe arranged centrally of the casing and extending trom a point near the bottom to near the top, the lower end of the same being connected to and in communication with the air supply pipe, spring actuated valve for controlling the admission of air to the vertical pipe, a spiral passage formed in the bottom of the casing with a central chamber directly below the vertical pipe, a drum removably mounted in the casing so as to pro vide an annular space therearound in comnnmioation with the outer space out the spiral passage and the space at the top of the easing, said vertical pipe terminating within and near the upper end of the drum,' a series of disks carried. by the drum, each one being provided with an opening through which the liquid may pass from the top to the bottom of the drum, said disks being so arranged as to have the openings in zigzag order, a loosely packed absorbent material filling the spaces between the disks, a Float controlled supply pipe in communication with the :tluid supply tank and the bottom of the casing, and another pipe extending from near the bottom of the casing to the top of the supply tank, as set forth.
